The brake equipment 14,15 of the present embodiment is magnet stopper, and during these brake equipments 14,15 are in "on" position, brake pad overcomes the elastic force of the spring be arranged on magnet stopper and separates with braked body 13, makes drg open.On the other hand, at brake equipment 14,15 when not being energized, and by brake equipment 14, the elastic force of 15 springs had, clamps braked body 13 by brake pad, to apply braking force to it.In the present embodiment, by brake equipment 14, during 15 no power, be called brake equipment action.
At multiple brake equipment 14, when only having an action in 15, also can brake lift car 3.Further, the total lock torque value of multiple brake equipment 14,15 is set to when making multiple brake equipment 14,15 action being simultaneously to realize emergency deceleration together, and the deceleration/decel of lift car 3 can not more than 1G (=9.8m/s
2).
In the lift facility 1 with said structure, in order to the opening and closing etc. of the lifting to lift car 3, car door and stop door controls and is provided with control panel 28.On the other hand, in order to when emergency braking to brake equipment 14,15 carry out controlling and being provided with control setup 7.In the present embodiment, control setup 7 and control panel 28 are provided separately, and make control setup 7 to control independent of the common operation undertaken by control panel 28 and to make brake equipment 14,15 carry out action.
For brake equipment 14, the control setup 7 of 15 has the automatic computer being equipped with CPU, ROM, RAM etc., is arranged in not shown Machine Room together with towing machine 11.Control setup 7 has abnormal detector 23, motion control device 24, table 25 and voltage hold circuit 26.
The rotational speed signal 31 of the governor 16 detected by the speed detector 21 of governor 16 is input in motion control device 24 with the detection signal 32 of the loaded weight detecting device 22 be arranged on lift car 3.Motion control device 24 calculates the speed of lift car 3 according to the rotational speed signal 31 of inputted governor 16.Further, motion control device 24 calculates its variable quantity based on the rotative speed of the governor 16 obtained according to the rotational speed signal 31 of governor 16, and calculates the acceleration/accel of lift car 3.On the other hand, motion control device 24 calculates the loaded weight of lift car 3 according to the load signal 32 that loaded weight detecting device 22 detects.
Abnormal detector 23 judges that whether the speed of the lift car 3 obtained according to the detection signal 31 of the rotary speed detecting device 21 of governor 16 by motion control device 24 and acceleration/accel are beyond prespecified limits value, when being judged as beyond limits value, to motion control device 24 output abnormality signal 33.In addition, when beyond rated weight by the prespecified lift car 3 of the loaded weight detecting device 22 be arranged on lift car 3, overload signal is exported to motion control device 24.
There occurs that towing machine 11 has there is abnormal heating in electrical motor, excessive moment appears in electrical motor etc. abnormal time, equally by abnormal detector 23 to motion control device 24 output abnormality signal 33.Abnormal detector 23 be judged as there occurs the exception of significant impact is produced to the operation of lift facility 1 time, in order to make brake equipment 14,15 actions, motion control device 24 output instruction signal 35,36.
When lift facility 1 there occurs abnormal, abnormal detector 23 is to motion control device 24 output abnormality signal, and now, motion control device 24 makes multiple brake equipments 14,15 action be arranged on towing machine 11.In the present embodiment, owing to making multiple brake equipment 14,15 interim actions, so motion control device 24 exports braking instruction 36 to the first brake equipment 14, and to being connected with this motion control device 24 and voltage hold circuit 26 output voltage hold instruction signal 35 for controlling the second brake equipment 15.
Voltage hold circuit 26 during receiving voltage hold instruction signal 35 from motion control device 24 to the second brake equipment 15 output voltage hold instruction 37.Now, motion control device 24 inquires about data bank and the table 25 of the voltages maintenance that 38 obtain in advance, and determines the maintenance moment of the voltage hold instruction signal 35 exported to voltage hold circuit 26.In the second brake equipment 15, during maintaining voltage hold mode according to the voltage hold instruction 37 from voltage hold circuit 26, make the second brake equipment 15 stop action, become drg open state.Thereby, it is possible to make the action again after the first brake equipment 14 action of the second brake equipment 15.
Store for making brake equipment 14 in table 25, the alphabetic data of 15 sequentially actions and the datum velocity of action commencing speed and reference acceleration etc.Say in more detail, in table 25, store the action commencing speed of each pattern of the second brake equipment 15 when tension force on the main hoist cable 4 acting on lift car 3 side and the ratio of tension force that acts on the main hoist cable 4 of counterweight 5 side are roughly 1 as datum velocity.
In addition, as described later, also store for according to the running state of lift facility 1 to the correction data of the action commencing speed that this datum velocity is revised.Revising data is the data drawn by testing in advance, and gives with the form of table or formula.These data have the increase along with warp tension ratio, the action commencing speed downward trend of the second brake equipment 15.
Be described referring to the action control of the diagram of circuit shown in Fig. 2 to two table brakes 14,15 be arranged on towing machine 11.Following process is in the flowchart of fig. 2 read regulated procedure by the automatic computer had by control setup 7 and is performed.
When there occurs the exception being judged as needing to make lift facility 1 out of service, the abnormal detector 23 of control setup 7 detects exception (step S101).The motion control device 24 of control setup 7 with reference to the data bank be stored in table 25, and controls the action of each brake equipment 14,15 according to the alphabetic data in data bank.
That is, motion control device 24 is to the multiple brake equipments 14 be arranged on towing machine 11, and the first brake equipment 14 in 15 exports braking instruction 36 (step S102).At this, multiple brake equipment 14,15 adopts identical specification, and can brake the electrical motor of towing machine 11 separately.First brake equipment 14, after input brake instruction 36, stops energising to start braking maneuver (step S103) at once.
Speed data Vb when being preset with in table 25 for making the alphabetic data of the first brake equipment 14 and the second brake equipment 15 sequentially action and making the second brake equipment 15 start action.Therefore, when outputing abnormal signal 33 from abnormal detector 23 to motion control device 24, in the second brake equipment 15, change "on" position into according to the voltage hold instruction 37 from voltage hold circuit 26, thus drg is remained on open state.
After making the first brake equipment 14 action in step s 103, the speed detector 21 be arranged on governor 16 detects the moving direction (rise or decline) of lift car 3 and the running velocity (step S104) of lift car 3.Meanwhile, by the loaded weight detecting device 22 be arranged on bottom lift car 3 to detect loaded weight (step S105).
Then, the motion control device 24 of control setup 7 obtains the variable quantity of the speed of lift car 3 according to the service direction of the lift car 3 detected in step S104 and running velocity, and calculates the acceleration alpha B (first half of step S107) of lift car 3.Owing to obtaining in advance in table 25 and storing the speed data Vb and reference acceleration data α b that make the second brake equipment 15 action, so motion control device 24 is with reference to the speed data Vb be set in table 25 and acceleration information α b (step S106).In addition, the action commencing speed VB of the second brake equipment 15 is obtained according to responsiveness data Vb
1, and the reference acceleration α making the second brake equipment 15 action is obtained according to acceleration information α b
1.Use acceleration alpha B and the reference acceleration α of the reality of lift car 3
1relation to calculated action commencing speed VB
1revise, and the last action commencing speed VB (latter half of step S107) calculating the reality of the second brake equipment 15.
Concrete correction and the calculated example of the action commencing speed VB in motion control device 24 are as follows.Reference acceleration α described in acceleration information α b is greater than at the acceleration alpha B of the lift car 3 obtained according to the detected value of the speed detector 21 be arranged on governor 16
1time, by slow for the record value that the action commencing speed VB of the second brake equipment 15 is slowed to specific rate data Vb.On the other hand, reference acceleration α described in acceleration information α b is less than at the acceleration alpha B of the lift car 3 obtained according to the detected value of speed detector 21
1time, the record value adding the action commencing speed VB of the second brake equipment 15 near specific rate data Vb is fast.
When abnormal detector 23 is about to make the first brake equipment 14 action to motion control device 24 output abnormality signal 33, due to the loaded weight of lift car 3, the tension force of the tension force of the main hoist cable 4 of lift car 3 side and the main hoist cable 4 of counterweight 5 side produces Tension Difference, and it is bad that rope sheave 12 likely can produce traction.Such as, there is above-mentioned situation when causing lift car 3 sharply to decline too greatly in the tension force in lift car 3 side.
Judge the magnitude relationship between the load of lift car 3 side and the load of counterweight 5 side.Weight due to counterweight 5 almost remains certain, so the load of counterweight 5 side is known number, therefore, is detected the load of lift car 3 side by loaded weight detecting device 22.The load of the load of the lift car 3 detected and known counterweight 5 is compared.
When the moving direction of lift car 3 is towards the side that load is large, action commencing speed VB is set as that a reference value of specific rate data Vb is slow.On the other hand, when lift car 3 moves towards the side that load is little, action commencing speed VB is set as that a reference value of specific rate data Vb is fast.That is, when lift car 3 side is heavier and lift car declines, the action commencing speed VB of the second brake equipment 15 is set as that the record value of specific rate data Vb is slow.In addition, heavier in lift car 3 side, and when lift car rises, the action commencing speed VB of the second brake equipment 15 is set as that the record value of specific rate data Vb is fast.The correction of above-mentioned action commencing speed VB is stored in table 25 with the form of table or formula.
In step S108, judge whether the speed of the lift car 3 obtained according to the output of the speed detector 21 be arranged on governor 16 reaches action commencing speed VB.When the speed of lift car 3 reaches action commencing speed VB, enter step S109.In step S109, motion control device 24, in order to make the second brake equipment 15 action, exports cold voltage hold instruction signal 35 to voltage hold circuit 26.Voltage hold circuit 26 cuts off the circuit (step S110) of self according to the cold voltage hold instruction signal 35 from motion control device 24.Thus, the voltage hold instruction 37 of the second brake equipment 15 is cut off, except the first brake equipment 14, and the second brake equipment 15 also action (step S111).In step S111, the second brake equipment 15 becomes no power state, and brake pad relies on elastic force to clamp braked body 13.
By the above process shown in Fig. 2, after abnormal detector 23 outputs abnormal signal 33 to motion control device 24, motion control device 24, according to the rising or falling speed of lift car 3, makes the first brake equipment 14 and the second brake equipment 15 sequentially action according to certain time interval.Thereby, it is possible to carry out emergency braking to lift facility as quickly as possible not causing in the offending situation of passenger.
The tractive property (tracing ability) of the towing machine 11 that lift facility 1 has and the moving velocity of main hoist cable 4 have correlativity.That is, the moving velocity of main hoist cable 4 is faster, and tractive property is lower, more easily skids between main hoist cable 4 and rope sheave 12.In addition, the acceleration change of main hoist cable 4 is larger, and the warp tension ratio produced is larger, more easily skids between main hoist cable 4 and rope sheave 12.
The acceleration change of main hoist cable 4 is determined by the lock torque of the moving direction of lift car 3 and the condition of service of the lift facility such as speed, loaded weight 1 and the first brake equipment 14 and the second brake equipment 15.Therefore, lift facility 1 is controlled, to avoid the acceleration change of main hoist cable 4 excessive, the skidding between main hoist cable 4 and rope sheave 12 can be suppressed thus.
In the present embodiment, the moving direction of operating lift car 3, speed and acceleration/accel is detected by the speed detector 21 be arranged on governor 16, and carried out the loaded weight of actual measurement lift car 3 by the loaded weight detecting device 22 be arranged on bottom lift car 3, so best braking can be carried out.That is, carry out correction computing according to the action commencing speed VB of above-mentioned detected value to the second brake equipment 15, can, according to the operation conditions of the reality of lift facility 1, make the second brake equipment 15 start action in suitable period.Thus, compared with when being set as certain value with the action commencing speed VB by the second brake equipment of the prior art, the skidding between main hoist cable 4 and rope sheave 12 can be suppressed better.In addition, reducing speed now lift car 3 stopping from the running velocity of lift car 3, stable braking force can be obtained, therefore, it is possible to reduce because of brakeage to the discomfort that passenger brings.In addition, stopping distance can also be shortened.
In the above-described embodiments, the first brake equipment 14 and the second brake equipment 15 are separately controlled.In addition, the first brake equipment 14 and the second brake equipment 15 adopt identical specification, have the ability making separately the lift car of lift facility stop.Therefore, even if when the brake equipment of either party there occurs fault, also can by the braking force of the brake equipment of the opposing party, the lifting of the lift car 3 of lift facility 1 be stopped effectively.
